Refinement of the diagnosis of a superficial basal cell carcinoma lesion with confocal microscopy and optical coherence tomography. Clinical image of an erythematosquamous lesion on the lower eyelid (a). The dermoscopic image (b) shows erythema and scaling, and the confocal image (c) (individual image; 0.5 × 0.5 mm) reveals a ‘streaming pattern’ of cells (elongated keratinocytes following the same axis) in the epidermis (white arrows). The optical coherence tomography image (d) shows epidermal hyporeflective thickening with dark borders and the correspondence to histopathology (hematoxylin–eosin stain) (e) revealing basaloid nests attached to the epidermis (yellow arrows).
